Farmington police said they have a DNA sample from the man suspected of stabbing Grace Burton in her home on June 21. She died several hours later in a hospital.

Farmington Police Chief Jack Peck told the Morning Sentinel of Waterville more than 70 samples have been taken so far and most eliminated the men as suspects. Police are awaiting the results of more tests.

Police said the suspect who stabbed Burton received cuts on his hands.

So far only one man has refused to give a DNA sample, but his attorney says he doesn’t fit the description of the suspect.
